NITED STATES PATENT HIRAM W. MCDONALD, OF'GALION, OHIO, AND MOTT W. MCDONALD, OF

ROCHESTER,

NEW YORK.

SPECIFICATION formingl part of Letters Patent No. 665,257, dated January 1, 1901.

Application led March 24, 1899l To all whom it' may concern:

Beit known that we, HIRAM W. MoDoNALD, of Galion, Ohio, and MOTT W. MCDONALD, of Rochester, New York, citizens of the United States, have invented certain Improvements in Sewer-Inlets, of which' the following is a specification, reference being had to the accompanying drawings.

Our invention relates to certain improvements in the construction of sewer-inlets, which improvements are fully described and illustrated in the following specification and the accompanying drawings, the novel features thereof being specified in the claims annexed to thel said specification.

In the accompanying drawings, representing our improvements in sewer-inlets, Figure l is a plan view. Fig. 2 is a front elevation. Fig. 3 is an end view. Fig. 4 is a front view of the grate. Fig. 5 is an end View of the same. Fig. 6 is a plan View of the same. Fig. 7 is a section on the line 7 7, Fig. 3. Fig. 8 is a section on the line 8 8, Fig. 1.

In the accompanying drawings, A represents the body, which is open at top and provided on its lower side with a suitable ring or pipe connection B.

O isthe adjustable curb-section.

D is the adjustable grate, and E the perforated gutter-grate. Y

The curb-section is closed on the top and sides except that it has an opening toward the street, which opening is crossed by the adjustable grate D. The curb-section is narrower than the body, and the space in the top of the body in front of the section is occupied by the perforated gutter-grate E. The ends of the curb-section are slotted, as indicated at F, Fig. 3, and the bolts and nuts I-I are employed to hold the curb-section in any de,- sired position of adjustment relatively to the body. This adjustment is indicated by the full and dotted lines in Figs. 2 and 3. The construction also admits of the curb-section Serial No. 710,333. (No model.)

beinginclined outward or inward,as indicated by the dotted lines in Fig. 3.

I I represent the curbstones set at each end of the inlet.

The grate D is of any suitable construction, being preferably made of wrought-iron. At each end the grate is provided with the heads J, having slots L, Fig. 5, which correspond with the slots F in the ends of the curb-section, so that both the section and the grate may be held in place by the same bolts H. Provision is thus made for adjusting the curb-section and grate relatively to each other or with relation to the body.

The gutter-grate E is provided at one end with the projecting lugN, which enters an opening in the end of the body, and at the other end with a perforated lug P, Fig. 8, into which the pin Q is inserted, so as to hold the grate in place. Outside 'the pipe connection B the bottom of the body is inclined upward, as indicated by the dotted lines T, Fig. 2, so as to prevent the accumulation of mud or sediment. The sides and ends, however, are continued downward, and a web U, Fig. 3, may extend down from the inclined bottom plates T. In this way a square base is given to the body, so that it may be firmly supported by the masonry.

We claiml. A sewer-inlet comprising an adjustable curb-box, and an adjustable and reinovable grate in the front of the curb-box.

2. In a sewer-inlet, the combination with the hollow body, of the adjustable curb-section open on the front side and the adjustable grate placed across the opening in the section, as and for the purposes set forth.

3. In a sewer-inlet, the combination with the hollow body, of the adjustable curb-section open on the front side, the adjustable grate across the opening in the section, and the removable gutter-grate, as and for the purposes set forth.

and the bofly, as and for the purposes set forth.
